Users also have this problem again. First of all, we should know the composition of the pump station. ad locum, Constant pressure water supply integrated pump set Manufacturer The pump set is divided into three parts. Main body of pump unit, external control equipment and internal equipment. First, we should select the wall thickness of the pump unit cylinder according to the actual demand. The factors to be considered here include: geology, temperature, working environment of pump unit, altitude, etc. Therefore, the selection of pump unit cylinder wall thickness should be summarized and considered. The wall thickness directly affects the firmness of the pump set. Of course, the selection of internal equipment is also important. During this period, the selection of submersible sewage pump is important. Here, the selection of flow head of submersible sewage pump is important. recommend Constant pressure water supply integrated pump set The flow head of submersible sewage pump shall be selected according to the actual situation. There are many types of submersible sewage pumps. For example, 200 in front of 200WQ300-7-15 refers to the diameter, WQ refers to the pump type, and 300 refers to the flow of 300m ³/ h. 7 refers to the lift of 7m, and 15 refers to the power of this submersible pump of 15KW.
1、 Constant pressure water supply integrated pump set Manufacturer Location selection. recommend Constant pressure water supply integrated pump set It is the core part of the water supply and fire fighting pipe network of the whole building or the whole community, plant area. The location of the pump room should be selected not only to facilitate the laying of the water supply and fire fighting pipe network, but also not to have noise impact on rooms with quiet requirements. It should also try to minimize the occupancy of valuable buildings (such as shops and parking spaces). The domestic water supply pump room and fire pump room should be built together, which can not only save land, but also facilitate maintenance management. For a residential area, the pump room is often designed in the equipment room of the underground garage, and is combined with the generator room and other electrical and air-conditioning rooms in the same fire compartment. And the pump room should be as close as possible to the middle of the large water users or the whole community, which can reduce the length of the main pipe and reduce the head loss of the pipe network. The outlet of the pump room shall be directly connected to the outdoor or the emergency exit. If the pump house is located in a civil building, it should not be adjacent to the neighbor's house or on its upper or lower floors, and the pump house should be located in a well ventilated room without freezing. The size of the pump room is determined by the layout of the living pool, fire pool and pump set.
recommend Constant pressure water supply integrated pump set What are the requirements for backfilling after installation? 1. Before backfilling, check that the pump station has not suffered structural damage. If yes, please contact our company as soon as possible and do not dispose of it by yourself! 2. After completing the installation and grouting of the pump station on the cement base plate and reaching the required strength, check that the structure is intact, and then backfill can be carried out. three Constant pressure water supply integrated pump set Manufacturer Backfilling must be carried out in time after installation to prevent the pump station from floating and toppling, and the FRP material cannot be pulled or squeezed by force. 4.32mm plain soil can also be backfilled with graded sand and gravel, and the particle size of gravel shall not exceed 32mm. When the distance between the pump station barrel and the edge of the foundation pit is less than 1 m but more than 0.5 m, only graded sand and gravel can be used for backfilling, and the gravel particle size shall not exceed 32 mm. When backfilling in winter and rainy days, check whether the backfill materials are stuck together. The backfilling of the foundation pit shall be carried out continuously and completed as soon as possible. During the construction, the ground water shall be prevented from flowing into the foundation pit to avoid slope collapse or damage to the foundation soil. Backfilling shall be carried out in layers. The height difference of each layer shall not exceed 50cm. It shall be compacted with a tamper or manually, and the compaction shall be more than 90%.
Constant pressure water supply integrated pump set Manufacturer The design principle is: (1) The overall layout should be reasonable, especially for the pump stations that combine irrigation and drainage or self drainage, self diversion and water lifting, as well as the pump stations that combine gates and stations, the layout should be as compact as possible, making full use of buildings for regulation. (2) The selection of pump type shall strive to make the design head of the pump station consistent with the rated head of the pump, and meet the requirements of irrigation and drainage flow. The pump type with advanced technology shall be selected as far as possible to ensure high efficiency of the pump station device and low operation cost. At the same time, the selected pump type should be relatively mature, with certain operation practice, and the test pump type should be avoided as far as possible. (3) The selection of pump type shall fully consider the use and working nature of the integrated pump station. For irrigation and make-up water pump stations with long annual working hours, pumps with wide range, high efficiency and good cavitation performance shall be selected. For those pumping stations focusing on drainage, the pump type with reliable working performance and simple structure shall be selected. (4) The project layout shall adopt positive water inflow as far as possible to ensure that the water inflow condition of each unit is good and the flow pattern is uniform. recommend Constant pressure water supply integrated pump set When lateral water inflow has to be adopted in the project layout, the distance between the lateral water inlet and the pump shall be extended as far as possible in the design, and certain diversion measures shall be taken. (5) The design of the outlet pool should try to avoid sharp bends that cause water impact and backwater. The pressure water tank shall be designed to avoid the increase of energy loss due to the mutual impact of water flow in each outlet pipe. (6) The construction materials available locally shall be used as far as possible. The design shall ensure simple and convenient construction and less project investment.
1. To ensure the safety of the pump room, the pump room must be locked. 2、 Constant pressure water supply integrated pump set Manufacturer Safety Operation Regulations, Hygiene and Safety Management System for Secondary Water Supply, Patrol Inspection Specifications, Water Quality Inspection Record System must be posted inside. 3 recommend Constant pressure water supply integrated pump set There must be the following record documents inside: Patrol Inspection Record, Water Tank Blowdown Record, Disinfection Record, Water Quality Inspection Record. 4. The pump room must be marked with the pressurized area, and the corresponding control system should also be marked with the pressurized area: low area, middle area, high area, etc, Mark the product model, qualified number, ex factory date, etc. 6. Water pump identification: the number of pumps must be painted on each pump; For example: 1 # pump, 2 # pump, 3 # pump, 4 # pump, 5 # pump, words. 7. "Normally open" signboard of inlet and outlet valves; 8. The pipe shall be marked with water flow direction arrow; 9. The prefabricated energy-saving pump room needs a drainage system 10. The energy-saving pump room can realize on-site control and remote monitoring;
